Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, wind mills for mechanical power, or wind pumps for water pumping or drainage. In this case the interest lies in generating electricity from the wind, in a low-cost and low-tech way.
To fully utilize the stronger air currents, wind turbines are fairly high. They are commonly placed in groups to generate reasonable output levels. Such generators are costly and there is a lot of criticism about their efficiency. Simpler devices, such as the water pumping wind mill on the left, need a lot of maintenance and may be prone to cyclones and other local tropical storms.
Worldwide a lot of research is going on in the developments of small-scale wind turbines and devices that can work at lesser heights. Solutions range from small wind mills that capture the lower velocities near ground level, up to installations on the balcony of your high-rise apartment to complement your own energy demand. It is this scale and simplicity that makes a certain technique applicable and affordable for more personal and customized use.
This assignment is focusing on the Wind Belt, which is an invention of Shawn Frayne. It makes use of the so-called ‘aero-elastic flutter effect’. A membrane, which is fitted between a pair of magnets, starts to oscillate between metal coils with even the slightest wind speed. Prototypes of the device are claimed to be 10 to 30 times more efficient than small wind turbines, at a cost price of only 10 U$!
One prototype so far has powered two LEDs, a radio, or a clock, using wind that was generated by a household fan. This research aims to scale up the device and enlarge the output.
